Present age of Sunita is 3 times the present age of
Nita. 4 years hence twice the age of Sunita will be equal to thrice the age of Nita. Find the present age of Sunita.Solution
Let present age of Nita = x So present age of Sunita = 3x 4 years hence, => 2(3x + 4) = 3(x + 4) => 6x + 8 = 3x + 12 => 3x = 4 => x = 4/3 Present age of Sunita = (4/3) Ă— 3 = 4 years
